Help with Mold identification

Hello all. was hoping you all might be able to help identify what this mold is, or at least point me to where I might find answers. We have a elderly cat which we found was peeing at spot outside the linen closet. We’ve been cleaning it with enzyme spray and noticed this growth on the other side of the door. It just on the perimeter of the pee area we have been cleaning. Any ideas?
